My son was diagnosed with milk allergy when he was 6 months old. He had bloody diarrhoea, milk spit ups and eczema as well. Doctors were confused between infection and allergy. Rectal biopsy showed infective cells but symptoms were like milk allergy. Docs didnt confirm allergy or infection. He was treated with antibiotics and was put on soya milk and dairy free diet. All symptoms were gone after that.Now he is 1 year and we are planning to reintroduce cow milk. I am really scared and have no clue how to reintroduce milk. I need advice on how to proceed and what precautions to take?
